Lord have mercy, I think my points weigh what your arrow does.  My arrows run 1700 or more grains at 38" and I draw 80+@36".  It's a full Manchu hunting setup.  I've dug a foot of arrow out of the ground after it went full through my target.  A 76# bow of mine with a similar setup put an arrow through both sides of a car door and dimpled out the metal on the outside of the opposite door.  

For your setup, finding a few more grains up front will help you, as you're gonna need the EFOC.  Getting it to 10GPP with point weight ought to get you an arrow that will drop anything in the US.  Your setup is plenty efficient, but I think those few extra grains won't go amiss.  I shoot mine just as much for historical preservation as I do because a 36" draw is standard for the equipment.

Sorry, double post.

Man are you Shaq? LOL! with my 150 gr broadhead i will be like 9.9 gpp..

halfseminole,don't they look for missing telephone poles in your neiborhood? 1700 grains that's wild! I'm going to switch out my 50 grain inserts with 100's to add some more weight up front, will put me right around 600.
